Katz, Grange, Nul., assigner, by mesne assignments, to SuperSagless Spring Corporation, Amsterdam, NX., a corporation of New YorkFiled Apr. 7, 1961, Ser. No. 101,386 22 Claims. (Cl. 5-67) Thisinvention relates to beds, and is particularly related to a bed havingan articulated bed frame coniprising a head section, a seat sectionpivoted to the bed section, and a foot section pivoted to the seatsection.

An object of this invention is to provide in a bed, an improved bedframe that could be converted from a iiat horizontal position to aposition in which the head and back support section would be elevatedfor viewing television or reading and at the same time the knees wouldbe elevated to a very comfortable position, in which the bed frame wouldsupport a mattress and means to lock the bed frame in an infinite numberof positions from completely flat to an almost upright position of thehead section.

Bed with bed frames having head, seat and foot sections that could bemoved from flat to various inclined positions have been known, but suchdevices as heretofore made were operated either by external sources ofpower which are expensive, or such devices had to be operated either byanother person or required the ccupant of the bed to get out of bed toadjust them which is very inconvenient.

It is hence another object of this invention to provide a bedconstruction 0f the character described, so constructed that thepositions of the sections of the bed frame can be changed solely by theoccupant unlocking the lock and shifting his Weight, thereby making thebed less expensive and easy and convenient to operate.

Still another object of this invention is to provide a bed comprising abed base, a lever pivoted to the bed base for angular movement relativethereto, and a bed frame comprising a head section, a seat sectionpivoted to the head section, and a foot section pivoted to the seatsection, said bed frame being connected to the lever for movement of itssections to various angular positions are relative to the others andrelative to said lever, whereby said bed frame in each of the variousrelative angular positions of its sections, can be moved as a wholerelative to the bed base, by moving the lever angularly relative to saidhead base.

Another object of this invention is to provide, in a bed of thecharacter described, a bed frame for a mattress, said bed frame having ahead section and a seat section, said sections being movable fromco-aligned positions to angular positions of less than 180, one relativeto the other, and means at the pivot corner for said sections, tosupport the portion of the mattress which overlies the pivot, and whichcannot it into the corner or apex of the angle between said sections,whereby the mattress on the bed frame (which bends to Conform to theangles of the sections of the bed frame) is better supported and henceadds to the comfort of the user.

Still another object of this invention is to provide in a bed of thecharacter described, means to lock the lever to the bed base, said meansbeing7 releasable manually, and separate means to lock the bed framesections against movement relative to each other and to the lever, saidlatter lock means also being releasable manually and inpedendently ofthe lever lock means, the construction being such, furthermore, thatback lock means are normally in locking condition and are unlocked onlywhile the operator is actuating them, and both said lock means revertingto locked condition when the operator stops actuating them.

Still another object of this invention is to provide a bed of thecharacter described having means to raise the seat and foot sections toa position higher than the back section, and means to move the bed frameto a position where the head, seat and foot sections are horizontallyaligned, means being further provided to hold the outer end of the headsection against movement below a predetermined height.

Yet another object of this invention is to provide in a bed of thecharacter described, highly improved means to prevent side sway ormovement of the bed frame in the various positions thereof.

A still further object of this invention is to provide in a bed of thecharacter described, highly improved locks for the lever and for the bedsections, said locks including push buttons, and said locks beingnormally locked, and being released only while the push buttons aredepressed.

Yet a further object of this invention is to provide a strong anddurable bed of the character described, which shall be relativelyinexpensive to manufacture, easy to manipulate, which shall be smoothand positive in operation, and yet practical and etiicient to a highdegree in use.

Other objects of this invention will in part be obvious and in parthereinafter pointed out.

The invention accordingly Consists in the features of construction,combinations of elements, and arrangement of parts, which will beexemplied in the construction hereinafter described and of which thescope of invention will be indicated in the following claims.

Referring now in detail to the drawing, l@ designates a bed embodyingthe invention. Bed itl comprises a bed base 1l. The base 11 comprises apair of parallel, horizontal, coextensive, symmetrical side members 12of angular cross section, each having a vertical upW-ardly extendingflange 13 at the lower end of which is a horizontal inwardly extendingyflange 14. Said side members 12 are supported in end legs 15 and may beinterconnected by usual suitable cross-members, not shown.

A head rest board 16 may be fixed to the head ends of .the bed base,extending upward-ly from the side memt bers Iand suitably fixed thereto.At the inside of the head rest 16 is fixed a horizontal -transverseangle shaped member 17 having an inwardly extending flange 18 and adownwardly extending flange 19, for the purpose hereinafter appearing.Member 17 is spaced above the side members 12, `as shown in thedrawings.

Fixed to opposed portions of ythe inner sides of the anges 13 of sidemembers 12, somewha-t closer to the head ends than foot ends of saidmembers, as by rivets 24), are brackets21, 21a (FIGS. 2,6, 8).

Bracket 21` has a lower portion 23 contacting the inner side of flange12, an intermediate outwardly bent portion 24 overlying the upper edgeof said flange, and an upper portion v25 ydisposed in a plane outside ofsaid flange, Portion 25 has an opening 26 with opposed flat edges 27(FIG.` l0), and round opposed edges 28 alternating with edges 27,non-rotatably fitted into opening 26 is a ref duced end hub 29 of a lockhousing 3l), having surfaces 27a, 28a contacting said surfaces 27, 28.Lock housing 3i? has an axial through opening 31 through which passesone end of a :rod 32. Extending from the hub 29 is an enlargedintermediate portion 33 having an outer circular surface 34. Extendingfrom the intermediate portion 33 is button orllange 35 `of greaterdiameter. Intermediate portion 33 is formed with three equiangularlyspaced, :radial drilled holes 36 having inner-frustoconical por-tions 37extending to the inner surface 31 (formed by the base of the drillpoint) thereby providing seats for balls 38 dropped into the holes. Theballs project through the holes 37a in the seats 37 tocontact the outersurface of rod 32.

The bracket 21a is symmetrically disposed relative to bracket 21` `andis similar thereto except that instead of being formed` with ropening 26as shown lin FIG. l0, it is formed with a round opening 4t), in whichthe other end ofrod 32 is journalled. SaidV rod 32 has flattened ends 41received in ysimilar shaped holes 42 in levers 43. Said ends 41 areriveted over and leversj43 are rotatable with trod 32.

The levers 43 are similar and aligned. Rod 32 is the .axis of rotationfor said levers. Each lever has a forwardly extending arm 44, the majorportion of which is located in a plane outside of the flane of flange13. The front end of each lever portion 44 lis offset outwardly, asshown in FIGS. 1 and 7. Extending rearwardly of the pivot points oflevers 43 are straight portions 46 in the plane of `portion 44.Extending from eachvportion 46 is an upw-ardly bent portion 47 yfromwhich extends an upwardly inclined arm 48. At the upper end of arm 48 isan outwardly offset end portion 49 in the planeof portion 45. As shownin FIGS. 2 and 3, arms 44 and portions 46 of the levers 43 are parallelto side members 12 and located thereabove, in one position ofsaid-levers.

Levers 43 may be rotated in clockwise directions from the position ofFIGS. 2 and 3 to the positions of FIGS. 4 and 5.

Rotatably mounted on the intermediate portion 33 of lock housing 3) is alock actuating arm 50. Arm 56 narrows forwardly. At its rear end ithasan inwardly offset portions 59a formed with anv opening 51 receivingsaid intermediate portion 33 andsurrounding surface 34 and confining theballs 3S to their openings or drilled holes 36. Opening 51 has threesimilar segments 52 of 120 each. Each segment is of greater radius atthe ends than in the middle. The middle of the segments substantiallycontact surface 34 of :intermedi-ate poi-tion 33. When the meetingendsof the segments 52 are over t the drilled holes 36, the balls 38 maymove lradially outwardly and are loose on the rod 32, and said rod to-vgether with levers 43 may rotate.` When saidV arm 5t? is rotated in aycounter-clockwise direction, `in the manner hereinafter explained,.toits normal position, the middle portions of segments 52 are over thedrilled holes 36, and the balls A33 are pressed radially inwardly toproject through openings 37a in the ball seals` 37, to grip the rod 32Iand prevent the lrod `from rotating, .and hence 'also keep the levers42 from rotating.

Means is provided to ynormally. retain the actuating arm Si) in positionfor locking levers 43. To this end, there is fixed to ange 13 of theside member which carries bracket 21, asby screws -orrivets 55, anupstanding bracket 56 having at its upper end, an inwardly offset linger57 formed with an opening 58 receiving a hub 59 fixed thereto and formedwith an axial through opening 60 for the purpose hereinafter appearing.Finger S7 overlies the small forward end of actuating arm 51D. Said armat its small end, has an upstanding finger 61 aligned withhub 59.Interposed between finger 57 and arm 59.

is a coil compression spring 62. Its upper end receives the lower end ofhub 59. Its lower end receives finger 61. Thus spring 62 presses down onarm 56 to retain the ,lock in locked condition. It is only when the armSilis rotated upwardly against the pressure of spring 62, in the mannerto be described.hereinaftenthat the lock is released, and the levers43released for rotation.

Means is provided to control rotation of levers 43 in a clockwisedirection looking at the drawing, to raise the forward ends 45'1of thelevers. To this` end,there is fixed` to the inner sides of portion 44 ofeach lever 43, a bracket 65 having a rearwardly extending tongue 66riveted to said portion as at 67. 'Extending inwardly from the ,forwardend of tongue 66 is an intermediate offset 68 from which extendsforwardly, a tongue 69 parallel to and spaced from said portions 44 andterminating close to portion 45 `of the lever. Pivoted to tongue 69as bypivot pin 70, is a link 71. Said link 71 has one end 72 received betweentongue 69 andlever portion 44. Beyond tongue 69, said link 71 has aninwardly extending offset 72 from which extends the outer end 73 ofthelink, inthe plane of said tongue 69. Tongue 69 is inthe plane of flange13 of side member 12, .as seen in FIG. 7. Pivoted to the outer end 72 oflink 71, as by transverse pivot pin 74are a pair of parallel links 75,76 disposed on opposite sides of link end 73.1 The lower ends of links75, 76 are oniopposite ends of flange 13 and arepivoted thereto by acommon transverse pivot pin 77 located only slightly forwardly of pivotpin when the lever 43 is in its down position. It will now'be understoodthat levers 43 may be swung up, when the ball lock is released, from thedown position of FIG. 2 to the upmost position of FIGS. 4 and 5. Thelinks 75, 76 being received on opposite sides of link 73, and portion 72of saidlink, being received between tongue 69 and lever portion 44,serves to stabilize the structure against sidey sway.

When levers 43 swing back,'the bent or curved portions 47 thereof dipbelow the upper redges'of flanges 13 of side members 12, as seen inFIGS. `4 and 5.

Supportedon and by the levers `43 is abed frame 843 comprising a head orend section 81, a middle or seat section S2 hinged tothe forward end ofthe head section, anda foot or leg section S3 hinged to the forward endof thek seat section. The head section S1 comprises a transverse angleshaped bar 84 having a top forwardly extending `flange 85 from the rearof which extends downwardly t above the lower edge of llange 36 of thebase, and crossbar 84 contacts the upper side of llange 13 of stop bar17 as shown in FIG. 2 ofthe drawing.

Flange 83 each side bar 87 terminates, at its forward end, short offlange 39 of said bar, as shown in FIG. 1.

The upper ends of portions 49 of the levers 43 contact the inner sidesof flanges 89 and are pivoted thereto by pivot pins 95.

The seat section 82 comprises parallel side bars 96 of anglecross-section, each comprising a top, inwardly eX- tending ange 97, andan outer, downwardly extending llange 98. At the far side of the bed,the forward end of flange 89 is pivoted, as by pin 99 to the rear end ofadjacent ange 9S. At the opposite side of the bed the llanges 89 and 98are interpivoted by a pin (not shown) coaxial with pin 99 but shorterthan said pin. Flanges 97 terminate -at their rear ends short of thepivots 99 (FIG. 1).

The bars 96 are interconnected by a pair of spaced cross-braces 9)similar to the cross-brace 96 described above, and located adjacent theouter ends of flanges 97.

Foot section 83 comprises a pair of side-bars 100` interconnected by afront cross-bar 101, all of angle shaped cross-section. Bars 199 havetop horizontal ilanges 192 and downwardly extending vertical flanges103. Cross bar 191 has a top flange 105 and a vertical downwardlyextending flange 106.

The rear end of llanges 98 are offset inwardly as at 93a to be locatedat the insides of llanges 89, as shown in FIG. 11. The forward ends ofanges 133 are in planes at the outsides of rear ends of anges 98 asshown in FlG. 15.

Fixed to the inside of each flange 98, adjacent its forward end, is abar 110 having an inwardly offset portion 111 spaced from the portion offlange 98 which extends beyond ange 97. Fixed to the inside of eachflange 193 is a bar 112 having an inwardly oiset portion 113 extendingrearwardly beyond flange 102 and spaced from flange 103. Flange 93 isreceived between flanges 103, 113. Flange 113 is received betweenflanges 98, 111. Flanges 103, 98, 113, 111 are pivoted by pivot pin 115.Thus, a pivotal connection and stabilizer is provided for the seat andfoot section, to prevent side sway of said sections.

Means is provided to connect the foot section to the levers 43. To thisend, the forward ends of levers 43 are connected to the side bars 199 ofthe foot section by pairs of spaced links 120, 121. Each link 129 ispivoted at its lower end, to portion 45 of lever 43 by pivot pin 123 andat its upper end by pivot pin 124 to ilange 133 of side bar 192. Eachlink 121 is pivoted at its lower end to the forward end of lever 43 bypivot 125 and at its upper end to said llange 103 by pivot pin 126. Thelinks 12@ are of greater length than links 121, and more inclined to thehorizontal when the bed frame is in the position or" FIG. 2. With suchconstruction, as the foot section 83 is pulled back from position of FG.2, to the position of FIG. 3, said foot section will incline downwardlyand forwardly as shown in FIG. 3.

When the levers 43 are in normal position, with arms 44 horizontal, andwith head and seat sections of the bed frame horizontal, the footsection will also be held in horizontal position by links 129, 121. Whenthe foot section is horizontal, the links 120, 121 are inclinedforwardly and upwardly. Pivot points 123, 125 are somewhat urther apartthan pivot points 124, 126.

Means is provided to releasably lock bed frame sections 31, S2, 83against relative movement in any relative angular positions thereof. Tothis end there is rotatably mounted on pivot pin 99 (at the right sideof the bed or the same side that has the releasable lock shown in FIGS.8, 10, l2) a lock housing 139 similar in shape to lock housing 33. Saidlock housing 134B has a through opening 131, through which pin 99passes.

Pin 99 has flats to engage in an opening with correspending tlats inflange 89 so that pin 99 will not rotate relative to said ange. Lockhousing 139 has an outer hub 139a with flats received in a correspondinghole 132 with ats, in portion 93a of `flange 93. Lock housing 139 has anintermediate portion 133 of circular shape formed with threeequiangularly spaced, radial, drilled holes 134 having annular seats 135at their inner ends providing holes 136. Balls 137 in the radial holes134 seat on the seats 133 and project through holes 136 to contact thepin 99. An enlarged inner hub or button 138 is provided at the innerside of lock housing 139. Rotatably mounted on intermediate hub 133 isthe rear end 140 of a lock arm 141. Said rear end 140 has a hole 142similar to hole 51. lt also presents three equal segmental edge portionsof less diameter at the middle and gradually increasing in diari etertoward its ends. When lock arm 141 is in its up position, themid-portions of the segments are over the drilled holes to press theballs radially inwardly into gripping position relative to the pin 99,thereby preventing rotation of sections 81, 82 one relative to theother. Actuating arm 141 narrows toward its forward end. It is formed,in its upper edge with a notch 144 to accommodate the llat end 91 of oneof the brace-bars 90. Upon rotating said arm 141 downwardly in acounter-clockwise direction, the ends of the segments of opening 142 arebrought over the drilled holes 134 allowing the balls 137 to moveradially outwardly, thereby 'releasing pin 99 and permitting rotation ofthe bed sections.

Means is provided to normally retain the actuating arm 141 in up orlocking position. To this end, a bracket 159 is fixed to the inside offlange 98 of side bar 96 adjacent the forward end of actuating arm 141.Said bracket extends down below flange 93 and has an inwardly extendinglinger 151. A pin 152 is iixed to the linger 151 and projects upwardlytherefrom. Said arm 141 is formed at its front end with a downwardlyprojecting lug 153 aligned with pin 152. A coil compression spring 155is interposed between finger 151 and arm 141, said spring receiving saidpin 152 at its lower end, and the lug 153 at its upper end.

Flange 97 is formed with a hole 156 directly above the narrow end of arm141. A push button 157 has its upper end slidably extending through saidhole. Said button has an enlarged base resting on the arm 141. Thespring 155 normally presses arm 141 upwardly, to retain the lock housingin locking or pin gripping position. However, upon pushing the button157 the arm 141 is depressed sutlciently to bring the lock housing toreleasing position. The lock housing remains in releasing position onlyas long as the push button is manually depressed. rhis constructionmakes sure that the bed frame sections will not move accidentally onerelative to the other unless and only while the push button 157 is beingdepressed.

Means is provided to release the lock housing 39 for the levers 43. Tothis end, there is pivoted to the inside of llange 93 on the same sideof the bed as arm 5u, as by pivot 161), alever 161 having a rearwardlyextending arm 162 lying beneath flange 93, and a forwardly extendingdownwardly inclined arm 163. Fixed to the inside of ilange 93 is abracket 164 having an inwardly offset linger 165 at its lower end formedwith an opening in which is mounted a hub 166 formed with a throughopening 167. A wire 163 has one end hooked through an opening 169 in arm162 and passes through opening 167 in hub 166 and then passes downthrough opening 6) in hub 59, through coil spring 62 and is connected orhooked to arm 53 through an opening 5917 therein. A lexible sleeve 170receives the wire 163 and is interposed between hubs 166 and 59.

Flange 97 of side bar 96 has a hole 175 in which is slidably mounted apush button 176 similar to push button 157 and overlying arm 162 oflever 161 and contacting said arm. Upon pushing button 17 6, lever 161is rotated in a clockwise direction (FIG. 5) to cause a pull on wire 16Supwardly to cause the wire to move through sleeve 170 to pull up arm 5t)to rotate the lock housing bushing 3G to releasing position. Suchmovement compresses spring 62, so that as soon as the operator takes hisfinger olf the push button 175, said spring will again pull down on thewire 168 to move the arm 5t) back to normal locking position.

It will now be understood that with the levers 43 in their normalpositions of FiGS. 2 and 3, button 1'76 may be depressed andthe bedsections moved from the flat horizontal coplanar positions of FIG. 2, tothe position of FIG. 3 or to any intermediate position between these twoextremes. The bed sections can be locked in any of these positions bytaking the finger off the push button 176. The person lying in the bedneed merely press down torwardly of pivots 95 (after pushing button 176)and the head section will rotate about said pivots in a counterclockwisedirection to cause the forward end of the head section to pulldownwardly and rearwardly in the seat section, which, in turn, pullsback on the foot section to cause it to move under control of links121i, 121. The push buttons 157, 176 may be provided adjacent theirupper ends with grooves receivingsnap rings 157a, 1'76a to prevent thepush buttons from falling out of their holes.

A mattress M may be placed on the bed rame.-

Also, usual springs or wires may be provided to interconnect the bars ofthe bed fram sections to provide a platform support for the mattress.

The position of FIG. 3 may be considered a sitting up position. Bykeeping the bed frame sections locked, and releasing the levers 143, thebed frame as a whole may be swung back. to the position of FIG. 4. Thisposition may be called a TN. position, that is, a position from which towatch television.

The position of FlG. 2 is for sleeping or lying down flat.

The position of FIG. 5 may be used for heart patients, since the footsection is raised above the .head and back section. This may be calledthe fully reclined position.

It will now be understood that the levers may be pivotally moved withthe bed frame sections locked in various relative inclined positions.

It will be observed that in many positions of the bed frame, the headsection has an angular position relative to the seat section of lessthan 180. kIn FIG. 4, this angle about 90. The mattress M cannot titinto the corner space formed at the junction of the head and seatsections. Means is provided to support the mattress above such cornerspace, to give ample support to the mattress at such location. To thisend there is pivoted to tianges S9 and 9S on each side of the bed, as bypivots 130, 131 spaced equi-distant from the pivot pin 99, downwardlyand inwardly inclined links 132,183, respectively. Supported on pivotpins 184, 185 at the lower ends oi said links, at each side of the bed,is a cradle 190. Each cradle cornprises a pair of similar symmetricalangular portions 191 located in a vertical plane interconnected by a tophorizontal portion or flange 192.` The anges 192, as both sides of thebedare interconnected by a cross-brace titl, such as heretoforedescribed.Y As the angle between the head section 81 and the seatsection becomes smaller, the top tlanges 192 cut across the cover formedby said sections, and the mattress Mwill be supported at said corner bysaid cradles 19t), and the mattress will not wedge into such corner. Thecradles 1% may be inter connected by wires or springs if desired.

Means is provided to limit upward rotation of levers 43, to preventlinks ,'71, 75 from becoming coaligned, to thereby insure that saidlevers can be swung down again,

and will not be locked in up position by said links. To`

this end, there is fixed to flanges 13 of one side member 12, a stop pin2Gb which willcontact an underedge of lever t3 as shown in FlGS. 4 and5, when the levers 43 have reached their maximum ydesired upswingpositions. -In suchposition the stabilizing links '71, 75 are still atan angle one to the other.

It will thus -be seen that there is provided an apparatus in whichtheseveral objects of this invention are achieved and which is wellAadapted to meet the conditions of practical use.

As possibleembodirnents vmightbe made of the above invention, and asvarious changes might bemade in the embodiment above `set forth, it isto bel understood that all matter herein set forth or yshown in theaccompanying drawings is to be interpreted as illustrative and not in alimiting sense. f j
